Introduction
During the author’s publication series on the Afrotropical
Cleomenini/Sestyrini (Bjørnstad 2013–2015) many mistakes,
inaccuracies and omissions have been discovered in the first four
papers (Bjørnstad 2013a, 2013b, 2013c, and 2014a). The aim of the
present paper is to rectify some of this. Also new material of the
genus Brachysarthron Thomson, 1864 has become available for study
necessitating the description of a new species. Collections

Sestyrini I (Bjørnstad 2013a)(1) p. 250 ff.: the correct name
for the epithet krameri (in Dere krameri) should be kramerae
since the person of attribution is a female (Ms. Ada Kramer).
According to the provisions of the Code (ICZN 1999), Article 19.2.
on “Justified emendations”, the correct name therefore should read:
Dere kramerae Bjørnstad, 2013 nom. emend. = Dere krameri Bjørnstad,
2013 syn. nov. (2) p. 263: the HT of Dere zimbabweana Adlbauer,
2000 is in the TMSA (not SANC)
Sestyrini II (Bjørnstad 2013b)The author did a serious mistake
in wrongfully interpreting the distorted scutellum of a specimen of
Hypargyra albilateralis ssp. similis (Gahan, 1898) as bifid, and
therefore concluding it was a representativ of the genus
Apiogaster. The whole article should therefore to be disregarded.
The formal rectification should be: Hypargyra albilateralis ssp.
similis (Gahan, 1898) = Apiogaster kudrnai Bjørnstad 2013 syn.

Sestyrini III (Bjørnstad 2013c)p. 76: After this paper was
published it became evident that the original series of syntypes
for Zoocosmius coeruleus Aurivillius, 1914 actually

contained three more specimens. These have been examined. In the
list for type material for Leptoderiana coerulea (Aurivillius,
1914) it should therefore read: PARALECTOTYPES: 2 ♂♂, 8 ♀♀ with the
same data as the LECTOTYPE in NHM.
Cleomenini IV (Bjørnstad 2014a)Karl Adlbauer and Pierre Juhel,
following the publication of pt. IV, both pointed out (pers. comm.)
that Brachysarthron inerme Aurivillius, 1925 does not in fact
belong to the genus Brachysarthron, but should be transferred to
the genus Cordylomera Serville, 1834. Further, that Cordylomera
inornata Duffy, 1952 is a junior synonym of this species. The
Zimbabwean HT of Cordylomera inornata Duffy, 1952 is deposited in
the NHM, London, and has been compared with the HT of
Brachysarthron inerme Aurivillius, 1925 in NRM, Stockholm and been
found to be conspecific. The necessary formal taxonomic changes
therefore should be: Cordylomera inerme (Aurivillius, 1925) stat.
nov. Brachysarthron inerme Aurivillius, 1925: 489 = Cordylomera
inornata Duffy, 1952 syn. nov. p. 77: New material of
Brachysarthron from Zimbabwe necessitates the description of a new
species, B. copei sp. n. The deletion of B. inerme and addition of
B. copei have as a consequence that the generic key given in
Bjørnstad (2014a) has to be revised (see Table 1)
Brachysarthron copei sp. n. (Figure 1) Holotype ♀ SE Zimbabwe:
Chiredzi, 30 km N of Triangle. 27.XI.1998. M. Snizek leg. in Coll.
JCS Description Size. Length 11 mm, width at shoulders 2.2 mm.
Head. Black and shiny. Mandibles with stiff,
yellowish britles, apex glabrous. Frons shallowly punctate,
weakly concave. Eyes excavate with suborbicular inferior lobe.
Antennal tubercles weakly raised, rounded. Vertex and occiput
shallowly punctate, but no transversal folding. Antennas. Black,
ventrally with a few stiffly erect or curved setae, dorsally with
very fine, short, adpressed pubescence. Scapus straight, swollen
apically. Antennomere 3 the longest, more than 1.5 times the length
of no. 4. Antennomeres 5 onwards increasingly flattened and with
one apical tooth on each joint. Pronotum. Black and shiny,
subglobose, only fractionally longer than wide, evenly convex both
laterally and dorsally, only shallowly punctate, glabrous.
Scutellum. Triangular with slightly rounded sides. Elytra. Dark
cobalt blue, very shiny basally, mat in the middle, then again
moderately shiny apically. The elytra are nearly parallel-sided,
but with rounded shoulders. Basally there is a small tubercle on
either side of the scutellum, then a depression from this towards
the shoulder. The elytra are shallowly punctate and nearly glabrous
except for a few erect bristles near the rounded apices. Legs.
Black with strongly clavate, acarinate femora. Metafemora nearly
reaching elytra apices. Tibiae straight (protibiae) or weakly
curved (meso- and metatibiae), distally widened. Metatarsi with
first joint twice as long as the second. The femora with only a few
scattered and short setae; tibiae and tarsi more densely setose.
Ventral surface. Gula glabrous, smooth and shiny, otherwise mostly
covered with a densely matted, silvery, adpressed tomentum. Last
visible tergite and sternite apically with long, erect yeollowish
bristles. Distribution. Only known from the type locality in
southeastern Zimbabwe.

Diagnostic characters. Closely related to B. antennatum. The
most important structural difference lies in the rounded elytra
apices, as opposed to the acutely spined apices in B. antennatum.
The pronotum in both species is strongly convex, but in B. copei
sp. n. the increase in width from the anterior margin is gradual,
while in B. antennatum the increase is irregular (cf. Figures 1–2
in Bjørnstad 2014a).
FIGURE 1. Brachysarthron copei sp. n. HT ♀ 11mm (JCS).
The scutellum in B. copei is shorter and boader than in B.
antennatum. In B. copei the subscutellar area of elytra is
irregularly tranversally wrinkled/rugose; not so in B. antennatum.
The elytra of B. copei are relatively shorter and broader than in
B. antennatum: the ratio length to width of each elytron is c. 6.5
in B. copei against 8.0 in B. antennatum. In B. copei all ventral
surfaces – with the exception of the glabrous gula – are densely
covered with matted silvery tomentum; in B. antennatum the
development of a ventral tomentum is much more reduced. The colour
differs: in B. copei the elytra are dark cobalt blue, as opposed to
the green or greenish blue of B. antennatum.
The Continental Cleomenini of the Afrotropical region: a brief
summary
Eight genera attributed to the tribe Cleomenini have till now
been described. All these have been revised or reviewed during the
past 12 years: Apiogaster Perroud, 1855 (Adlbauer 2003), Ochimus
Thomson, 1860 (Adlbauer 2004), Dere White, 1855 (Bjørnstad 2013a),
Leptoderiana Bjørnstad, 2013 (Bjørnstad 2013c), Brachysarthron
Thomson, 1864 (Bjørnstad 2014a), Iridoclava Bjørnstad, 2014
(Bjørnstad 2014b), Hexarrhopala Gahan, 1890 (Bjørnstad 2014c), and
Zosterius Thomson, 1864 (Bjørnstad, 2015). Apiogaster (21 spp.) and
Dere (16 spp.) are by far the largest genera, and together
constitute more than three quarters of the 49 species of the
Afrotropical Cleomenini described till now. Very likely this number
will increase: more than one third (17 spp.) has been described
from the year 2000 onwards. Most of the Cleomenini species seem to
be both diurnal and nocturnal in their activity pattern. Many
species are colourful and/or metallic and visit flowers for pollen
or nectar. The members of the Cleomenini are found all over
Sub-Saharan Africa.
